I really want to give a shout out to all of the women who have managed to exclusively breast feed even though they work. I pumped for a solid year and feel really good about the fact that my daughter got only breast milk (until she ate food). At times I worried about my supply being low, but I got up early to pump, I pumped even on the weekends, I drank Mother's Milk tea and even took fenugreek.
This is the way I think of it: I would only put my daughter in the safest car seat, so why not give her the best food? No matter what the companies say, formula can't match the genius of mother's milk.
